Abstract: BACKGROUND: Vitiligo, although asymptomatic, highly compromises patients´ quality of life (QoL). Therefore, an adequate evaluation of QoL is essential. OBJECTIVES: Translation, cultural adaptation and validation of VitiQol (Vitiligo-specific health-related quality of life instrument) into Brazilian Portuguese. METHODS: The study was conducted in two stages; the first stage was the translation and cultural/linguistic adaptation of the instrument; the second stage was the instrument´s validation. RESULTS: The translated VitiQol showed high internal consistency (Cronbach alpha = 0.944) and high test-retest reliability and intraclass correlation coefficient=0.95 (CI 95% 0.86 - 0.98), p
